Filed: 1971-07-01
Abstract: 1315758 Carbonized amidrazone-type polymers AKZO NV 1 July 1971 [1 July 1970] 30935/71 Heading C1A Shaped articles are made from polyacylacylamidrazones and such polymers containing one or more chemically bonded metals by shaping the article from the polymer and carbonizing it. The article may be a continuous mono- or multi-filament, a thread, yarn, cord, knitted fabric, woven fabric, web, paper or felt. The polymers are made by reacting a carboxylic acid bisamidrazone, e.g. oxalic acid bisamidrazone with one or more dicarbonyl halides in a solvent system in the presence of one or more acid acceptors. The carbonization may be effected batchwise or continuously by heating in the range of 360 to 1000‹ C. preferably in an inert atmosphere, e.g. nitrogen, by passing the shaped article, e.g. a fibre, continuously through an oven comprising heating zones of increased temperature. If desired the fibre may subsequently be heated in the range of 1000 to 3000‹ C. in a noble gas atmosphere. The filamentary articles may contain conventional textile additives and other synthetic and natural polymers such as polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylates and regenerated cellulose. Exemplified polymers are polyterephthaloyloxamidrazone, polyfumaroyloxamidrazone, poly - 2,5 - pyridinedicarboxyloxamidrazone, and a mixture of polyterephthaloyloxamidrazone and regenerated cellulose. Young's modulus and tensile strength values are given for carbonized yarns formed from the above polymers. The fibres may be drawn.

Abstract: 655,357. Statistical apparatus. RUSSELL, E. W. C. Nov. 26, 1947, No. 31272. [Class 106 (i)] [Also in Groups XV and XL (b)] A magnetic record has its recording area covered by an evenly-magnetized or magnetizable material interrupted by spaces devoid of magnetic or magnetizable material which by their shape, size, or location represent the recorded intelligence. A statistical record card 18 is coated with a magnetizable material together with a suitable binder, e.g. iron oxide and lacquer. The code perforations 20 are impressed by a standard punching-machine either before or after adding this coating. The card is then evenly magnetized and may be scanned electromagnetically or may operate standard punchedcard tabulating equipment by mechanical or photo-electric means. A card prepared and punched in the above manner may be affixed to an unpunched support, e.g. a second card, on the back of which may be printed or inscribed any desired visual information. In a further modification a card is punched and used as a stencil through which masking material such as soluble wax is applied to a further tape. This tape is then coated with magnetic material and the wax and coating removed from the waxed portions by a suitable solvent such as benzene. Telegraph tape may be prepared in the same ways (see Group XL (b)) and a magnetized punched card may be incorporated in a passport or like document (see Group XV). The Provisional Specification states that records may be prepared by perforating cards or sheets which are themselves magnetic.

Title: Boron-12 beta decay neutron detector
IPC: G01T3/00
Filed: 1964-08-04
Abstract: 1,002,880. Detecting neutrons. UNITED STATES ATOMIC ENERGY COMMISSION. Aug. 4, 1964 [Oct. 18, 1963], No. 31338/64. Drawings to Specification. Heading G6P. A neutron flux measuring instrument contains a boron-11 sensitive element. This is surrounded by a stainless steel envelope and the current passing between the boron and steel, which is a function of the flux, is measured. The (n,γ) cross-section for boron-11 is less than 0À05 x 10<SP>-24</SP> cm.<SP>2</SP> so that the consumption of this isotope is low. The boron-11 is changed to boron-12 which decays to carbon-12 by #- emission with a short half-life and a maximum energy of 13À4 Me v. Thus, the # current can follow rapid changes in neutron flux and can penetrate large thicknesses of ceramic insulator round the boron.

Title: Improvements in or relating to a method and an apparatus for narrowing plain stitch or rib fabric on a flat knitting machine
IPC: D04B7/04
Filed: 1962-08-15
Abstract: 991, 943. Knitting-machines. EDOUARD DUBIED ET CIE S.A. Aug. 15, 1962 [Aug. 18, 1961], No. 31368/62. Headings D1C and D1K. A fabric of plain or rib stitches is narrowed on a flat bed knitting machine by the successive transfer of selected stitches and the attachment thereof to neighbouring stitches by the use of small auxiliary beds superimposed on the main beds, the small auxiliary beds being arranged in pairs on both sides of the machine in a symmetrical arrangement with respect to the middle thereof. Transfer needles are provided in the main needle beds and the auxiliary beds are adapted to receive the stitches of groups to be displaced. In Fig. 1 all stitches are carried in the rear bed but the outermost stitches are carried in the needle groups 9-14 and 17-22 which are in the auxiliary beds. As the machine carriage moves from right to left in Fig. 2 the stitches of needles 23 and 15 of the main bed will be transferred to the needles 39 and 31 of the front bed. On the return of the carriage (Fig. 3) these stitches are transferred from the needles 39 and 31 to the needles 16 and 24 of the rear main bed (Fig. 4). The innermost stitch on the auxiliary bed is brought into alignment with the outermost needle on the fabric middle zone in the main needle bed by upward pivotal movement, lateral displacement and downward pivotal movement of the auxiliary bed following each narrowing. This movement results in the needles 22 and 14 occupying the positions previously occupied by needles 23 and 15 of the main bed which are taken out of operation (Fig. 5). The stitches in the marginal zone are laterally inclined owing to transverse tension in the fabric as it carries out of the machine so that they may be transferred. The displacement brings the innermost needle of the group of the marginal zone to the needle carrying the outermost stitch of the central zone in which zone the stitches have a substantially perpendicular position permitting transfer without difficulties.

Title: Improvements in embossing or imprinting machines
IPC: B41F17/00
Filed: 1925-12-19
Abstract: 260,443. Link, R. P. Dec. 19, 1925. Embossing; holders for loose type.-In cutter-crush embossing-machines the hollow-faced types or dies are supported on bars which are mounted in side plates movable relatively to the bed supporting the paper, card, &c., to carry the types or dies towards or away from the bed. the side plates being moved by means of draw-bars slidably mounted on the bed. The bed 10, Figs. 1 and 4. which is adapted to be supported on the lower ram plate of a press, is provided with side pins 14 engaging vertical slots 5 in the side plates 11 which support type-carrying bars 12 extending between them. The draw-bars 17 are disposed between the sides of the bed 10 and the side plates 11. with their upper edges engaging beneath flanges on the side plates 11. as shown in Fig. 5. The draw-bars are provided with inclined cam slots 16 engaging the pins 14 on the bed 10. so that the action of withdrawing the bed from beneath the upper ram plate, by pulling the handle 18, gives the draw-bars a vertical movement relatively to the bed, causing the side plates 11 to lift and raise the typesfrom the face of the bed. The abutting edges of the draw-bars 17 and the side plates may be cammed to increase the vertical movement of the latter. By making the bed 10 of equal width. to the lower ram plate and extending the drawbars downwardly below the bottom of the bed the draw-bars act as lateral guides for the bed. The type-supporting bars 12 are slidable within longitudinal slots in the side plates 11 and have slight end play, means being provided to clamp them in position. The ends of the bars 12 are grooved to receive an aligning-bar 20 which is slidable vertically on pins 21 and is held down. by a leaf spring 22. Alternatively, the aligning- bars may be secured by clamping-screws. The type-supporting bars 12 are provided with shoulders 12a, Fig. 4, along each edge to support flanges on the types 13, the bars 12 acting as space bars for the lines of type. The thickness of the bars 12 is preferably less than the full height of the type, so that when their faces rest upon the card &c. upon the bed 10, the backs. of the types project above the top surfaces of the bars 12, thereby allowing the faces of the types to be pressed into the card &c. until their backs are in alignment with the top surfaces of the bars 12.
